I have got a vw-transporter turbo diesel.
Sometimes when I want to start it and turns the key, nothing happens except that I hear a click.
If I put it in 4. gear, and let it roll a bit and turns the key at the same time, it the startermotor starts immediately.
I have had the same problem with a Golf II once, just before the car was dumped.
What is the problem here ? Starter motor brushes contact problem ?
(sorry for my english)
